BigCommerce Integrations: How to Connect Your Store to ERP, CRM, 3PL and POS Systems

A BigCommerce store rarely runs alone. Behind it sits an ERP holding your stock and pricing, a CRM holding your customer history, a 3PL shipping your orders, and a POS ringing up sales in a physical shop. When those systems do not talk to each other, someone on your team spends their week copying numbers between them, and every copy is a chance to get it wrong.

This guide covers the integrations that matter for a growing BigCommerce store, the three ways to build them, what each approach costs, and what tends to break. It is written for the person who has to make the decision, not for a developer who already knows the answer.

BigCommerce integrations connect your store to the systems that run your business, such as ERP, CRM, 3PL, POS and marketing tools, so orders, inventory and customer data move automatically instead of by hand. You can connect them three ways: a native app from the BigCommerce marketplace, an iPaaS connector like Celigo or Jitterbit, or a custom API build when your setup does not fit a standard app.

What Are BigCommerce Integrations?

A BigCommerce integration is a connection between your store and another piece of software, built so data moves between them without a person in the middle. When a customer places an order, an integrated setup pushes that order to your ERP, reserves the stock, sends the shipment request to your 3PL, and updates the customer record in your CRM. Nobody retypes anything.

BigCommerce lists over 1,200 apps and integrations in its marketplace as of September 2026, organised into categories including ERP, CRM & Customer Service, Shipping & Fulfillment, POS and In Store, B2B and Wholesale, Accounting & Tax, and Sales Channels. Most stores need somewhere between three and six of them. Beyond the marketplace, anything with an API can be connected, so the practical number is far higher than the catalogue suggests.

Is BigCommerce Still Called BigCommerce?

Yes, the platform is still BigCommerce. What changed is the company behind it. On 31 July 2025, BigCommerce Holdings, Inc. renamed itself Commerce.com, Inc. and launched Commerce as the parent brand covering three products: BigCommerce, Feedonomics and Makeswift. The Nasdaq ticker changed from BIGC to CMRC on 1 August 2025.

For store owners, nothing about your integrations changed. Your apps, your API and your admin all work the same way. It matters here only because you will see both names in documentation and vendor material, and because Feedonomics and Makeswift now sit alongside BigCommerce under one roof, which affects how you think about product feeds and storefront editing.

Why Do BigCommerce Integrations Matter?

Three reasons, in the order they usually bite:

• Manual work does not scale. Copying orders into an ERP is survivable at 40 orders a day and impossible at 400. The break point arrives faster than most owners expect.
• Disconnected data goes stale. If your store’s stock levels update overnight rather than in real time, you will oversell. Overselling costs you the margin on the order plus the customer.
• Your team works around the gap. Spreadsheets appear. Then someone leaves and takes the spreadsheet’s logic with them.

There is a customer experience argument too. Forbes reports that 81% of customers prefer companies that offer a personalized experience, and personalisation depends entirely on whether your systems share what they know about a buyer. You cannot personalise from data your store cannot see.

Which BigCommerce Integrations Does Your Store Actually Need?

Start with the table, then read the sections that apply to you. Effort assumes a store with a clean catalogue; messy data adds time to every row.

1. BigCommerce ERP Integration

This is the integration that changes how a business runs, and the one most likely to be quoted in five figures. Your ERP is the system of record for stock, cost, pricing and financials. Connecting it to BigCommerce means your storefront sells against real inventory and your finance team stops reconciling two versions of the truth.

What usually gets synced: product and SKU data from ERP to store, stock levels in near real time, tier pricing or pricing set per customer account, orders from store to ERP, and invoice or fulfilment status back to the customer account.

Common systems we see on BigCommerce: NetSuite, Microsoft Dynamics 365, Acumatica, Brightpearl, SAP Business One, Sage 300, Sage 50, Syspro and Katana. NetSuite and Dynamics have the deepest connector ecosystems. Syspro and Sage 300 almost always need a custom or iPaaS build, which is worth knowing before you budget. If you want this handled end to end, our BigCommerce ERP integration services cover scoping, mapping and build.

2. BigCommerce CRM Integration

A CRM integration puts order history next to the sales conversation. Your support team stops asking customers for order numbers, and your sales team can see what someone bought before they pick up the phone.

Salesforce and HubSpot both have mature BigCommerce connectors. Zoho CRM and Keap suit smaller operations. Zendesk sits slightly differently, since it is support rather than sales, but the integration pattern is the same: push the customer and order record in, pull the ticket status back.

3. BigCommerce 3PL and Logistics Integration

Once you outsource fulfilment, the integration is not optional. Your 3PL needs orders automatically and you need tracking numbers back before the customer emails to ask. The same principle applies to eCommerce warehouse management if you hold stock yourself.

ShipStation and ShipBob are the common choices and both have native BigCommerce apps. Shippo and Easyship compete on rate shopping. ShipperHQ handles complex shipping rules such as multiple origins, oversized items and freight, which is where most standard apps run out of road. Amazon FBA works as a fulfillment source for BigCommerce orders through multichannel fulfillment.

The detail that catches people out is returns. Many 3PL integrations push orders out cleanly and handle returns badly. Ask about the returns flow specifically before you sign.

4. BigCommerce POS Integration

If you sell in a shop as well as online, POS integrations are what stop you selling the same unit twice. They unify stock across both channels and, done properly, unify the customer too, so someone who buys in store shows up in your online marketing lists.

Clover, Zettle, Epos Now, Revel Systems and Hike all connect to BigCommerce. The decision usually comes down to whether your POS or your ERP is the master for inventory. Pick one. Two systems both believing they own stock is the most common cause of a POS integration failing six months in.

5. BigCommerce Marketing Integration

The cheapest integrations on this list and often the fastest payback.

Email Marketing Integration

Klaviyo and Mailchimp both connect natively and pull order and browsing data into segments, which is what makes abandoned cart and post purchase flows work. Without the integration, your email tool is guessing.

Advertising and Social Integration

Push the same data to your ad platforms. Meta and Google audiences built on actual purchase history outperform audiences built on page views, and BigCommerce native connections handle most of it without custom work. This pairs directly with the wider eCommerce growth strategies you are already running.

Marketing Automation Tools

Automation platforms let you trigger campaigns from real behaviour: a second purchase, a lapsed customer, a valuable cart abandoned at checkout. The integration is what supplies the trigger. Discount codes and loyalty programmes can be automated the same way.

6. BigCommerce DXP and Headless Integration

BigCommerce supports headless architecture, so you can keep it as the commerce engine and serve the front end from something else: Acquia, Sitecore, Kentico Xperience, or Makeswift, which now sits under the same parent company.

This is the heaviest integration on the list and the one most often chosen for the wrong reason. Go headless when your content needs genuinely exceed what a BigCommerce theme can do, or when you are serving several storefronts from one catalogue. Do not go headless because it sounds modern, because you are taking on a front end you now have to maintain. Our headless BigCommerce development team will tell you plainly when it is not worth it.

7. BigCommerce Analytics and Business Intelligence Integration

GA4 covers behaviour. It does not cover margin. If you want to know which products actually make money after shipping and discounting, you need store data joined to cost data in a BI tool such as Looker Studio, Power BI or Tableau.

This is usually the last integration a store builds and the one owners wish they had built first.

8. Multichannel Inventory Integration

Selling on BigCommerce plus Amazon, eBay, Walmart or a physical shop means one stock pool and several places to sell it. Zoho Inventory, Ordoro, inFlow and Fishbowl manage that pool. Feedonomics handles the product feed side, getting accurate and well formatted listings onto each marketplace.

If you already run an ERP, check whether it can be the inventory master before you add a separate tool. Fewer systems is almost always the right answer.

How Do You Connect a System to BigCommerce?

Three methods. Most stores end up using more than one.

A practical rule: start with the native app. Move to iPaaS when you have three or more systems to connect or your ERP has no decent app. Go custom when a specific business rule such as pricing set per customer account, contract catalogues or complex tax cannot be expressed any other way. If you are weighing a custom route, our guide to BigCommerce app development covers what building on the API actually involves.

How Much Does a BigCommerce Integration Cost?

Very few published guides put numbers on this, so here are honest bands. These are ranges for the build, not for software licences, and they assume North American agency rates.

What moves a project up a band: dirty product data, pricing set per customer account, multiple warehouses, a legacy ERP with a SOAP only API, and any requirement for real time rather than scheduled sync. What keeps it down: a clean catalogue, a modern ERP with a documented REST API, and a willingness to accept a fifteen minute sync instead of an instant one.

How Do B2B Stores Integrate BigCommerce With an ERP?

B2B is where integration stops being a convenience and becomes the product. A B2B buyer expects to log in and see their negotiated prices, their contract catalogue, their credit terms and their order history. None of that lives in BigCommerce. It lives in the ERP.

That means a B2B eCommerce development project has to handle things a B2C one never touches: customer group pricing and pricing set per account, quantity break pricing, restricted catalogues per account, credit limits and payment terms, purchase order numbers on checkout, and quote to order flows.

BigCommerce B2B Edition covers a good portion of this natively. Where it stops is usually pricing complexity. If your pricing logic lives in your ERP and is more complicated than a simple tier, expect a custom or iPaaS build to bridge it in real time.

BigCommerce ERP Integrations We Have Built

Three engagements where the integration was the hard part:

• Enterprise Magento to BigCommerce B2B migration with ERP integration. A B2B replatform where the ERP connection carried pricing and catalogue rules through the move.
• Generation Pet: Shopify to BigCommerce B2B migration with real time ERP integration. Real time rather than scheduled sync, on a B2B catalogue.
• Parts Connexion: 92% conversion rate increase after BigCommerce migration and custom integrations. Custom integrations built alongside the migration, with a 92% lift in conversion rate.

What Should You Look for in an Integration Platform?

If you are choosing an iPaaS or an app rather than building custom, these are the things that determine whether it still works in two years:

1. Field level mapping you can change yourself, without a developer and without a support ticket.
2. Error handling that tells you what failed and lets you retry it. Silent failures are how stores discover a week later that nothing synced.
3. Sync frequency that matches your business. Real time costs more than every fifteen minutes; decide honestly which you need.
4. Historical data migration, not just sync going forward. Ask whether it backfills.
5. Sandbox testing against a staging store before anything touches production.
6. A clear answer on support, covering whether that is the app author, the iPaaS vendor or you.

Final Thoughts

Most integration projects go wrong in the mapping, not the code. The systems connect; it is the decisions about which system owns stock, how pricing is resolved, and what happens when a sync fails that determine whether the build still works a year later.

WebDesk Solution has run BigCommerce ERP, CRM, 3PL and POS integrations for B2B and B2C stores across North America for 14+ years, including real time ERP syncs on live B2B catalogues. As an experienced BigCommerce development company and eCommerce development partner, we will tell you honestly whether you need a native app, an iPaaS connector, or a custom build, and roughly what it costs.
